3 reasons to worry about the FBI's facial recognition program

The FBI quietly developed a facial recognition network that allows law enforcement to identify people in the United States without their knowledge. Now lawmakers want to know why the agency didn't tell people about it. "Why did the FBI not fulfill the requirement of the law?" asked House Oversight Committee chairman Jason Chaffetz at a hearing on Wednesday. The FBI didn't let citizens know the agency was collecting photos from motor vehicle departments, according to a report from the Government Accountability Office. And a lot of people can be found on law enforcement facial recognition networks -- around half of American adults, according to a study from Georgetown University's Center on Privacy and Technology.
